Energy-efficient heating and cooling in this building are provided by passive chilled beams served by a heat pump linked to a reservoir for heat supply and rejection.

The newly built operations centre of Essex & Suffolk Water at its Hanningfield Water Treatment Works near Chelmsford has achieved a BREEAM ‘Excellent’ rating with the help of a water source heat-pump system to provide heating and cooling via SAS integrated service modules fitted with passive chilled beams. The water source is the nearby Hanningfield reservoir.

FaulknerBrowns Architects, Hoare Lea and SAS Project Management collaborated on the project. Steve McIntyre, a partner with FaulknerBrowns comments, ‘The design of Sandon Valley House implements the design principles set out in the British Council for Offices guide. We have designed an office workplace that combines best practice in office design with a number of environmentally sustainable building systems, such as reservoir heating and cooling. The design has resulted in increased workplace productivity and a building solution which is extremely energy efficient. These issues were key components of our client’s original brief.’

Jenny Abel, facilities team leader at Essex & Suffolk Water, adds, ‘The beams across the ceiling not only work well but look great too. Integrating the chilled beams and lighting also creates a simple and clean design. Sustainability is at the heart of the design of Sandon Valley House, so the energy efficiency of the chilled-beam system is key to us.’
